“Is Air Pollution a Belief?” Winter-Koger’s essay “What on Earth Are We Doing?” discusses many environmental problems, e.g.: ozone depletion, global warming, overpopulation, deforestation, air and water pollution, topsoil loss, and coral reef destruction. While it is difficult to isolate one problem to discuss, as they are all equally, important environmental problems; I have decided to research the effects of outdoor air pollution. I am interested particularly in whether the United States has made any positive changes for cleaner air, or added to the negative impacts on two of six different types of air pollution-ozone(smog) and particle pollution (particulate matter) since Winter-Koger’s essay (2004). Air pollution is one of the many environmental problems faced each day around the world. Man has always been a solid contributor to environmental pollution, a problem passed on from generation to generation. Air pollution is not a belief that one has; but a real problem that absolutely does exist. Many people have dedicated their lives to finding a solution to the detrimental effects of air pollution. And many people, unknowingly, and some ignorantly, have dedicated their lives to contributing to air pollution. To better understand the effects of air pollution, one must first understand the definition of air pollution and how it is caused. You may disagree and feel you know the definition of air pollution; but ask the person next to you to define air pollution, and soon you will find that many people do not have a true understanding of air pollution. Air pollution occurs when high levels of gases, chemicals, fumes, and dust released into the air have become harmful to humans and living organisms, and damages structures and the environment. There are six pollutants, also known as greenhouse gases (except for lead) that contribute to air pollution: ozone, carbon monoxide, lead, nitrogen dioxide, particulate matter (also known as particle pollution), and sulfur dioxide Ozone, O, another word most of us are aware of but unsure of its definition, is an unstable, poisonous allotrope-having 3 atoms-of oxygen that is highly reactive, and the primary cause of smog. According to Professor Bassam Z. Shakhashiri’s website, ozone is commercially used as bleach for waxes, oils, and textiles, and as a deodorizing agent; it is also used to sterilize the air and our drinking water. Ozone is highly reactive when combined with nitrous oxide, NOx, and hydrocarbons, or volatile organic compounds, VOC, heat and sunlight. NOx is emitted when fuel is burned by cars and trucks and VOC is emitted from factories, power plants and other sources. Hot, sunny days make quite the combination for higher levels of ozone in areas of higher congestion and industrial areas. Higher levels of ozone has been the cause of great concern as it causes many pulmonary problems ranging from irritation of the respiratory tract to asthma attacks, coughing, wheezing, and shortness of breath, chest pain when inhaled deeply and in some cases, premature death (ALA). The American Lung Association, ALA, closely monitors ozone levels effects on senior citizens, teens, children, and people already suffering with asthma and other chronic lung diseases. Set by the Environmental Protection Agency, EPA, in 1997, the last time the acceptable ozone level at ground-level had been changed, ozone levels measured at 80 parts per billion (ppb). In 2008, the EPA realized this level was too high and tightened restrictions in an effort for safer levels of ozone. Since Winter-Koger’s essay, the levels of ozone in the United States have decreased year after year. Year | Mean (ppb) | 2002 | 0.08794186 | 2003 | 0.0818876 | 2004 | 0.07460853 | 2005 | 0.07982946 | 2006 | 0.07824806 | 2007 | 0.07855814 | 2008 | 0.07471705 |

Regardless of the yearly decrease, in January of 2010, two years after changing the accepted level of ozone, the EPA is reconsidering lowering the levels anywhere from 60-70 ppb, a level providing better protection for not only children, senior citizens, and those already suffering from pulmonary health problems, but vegetation. Even though the outcome will not be known in time for my research paper as a deadline for any written proposals to be submitted to the EPA have a deadline of March 22, 2010, and a decision will not be made until all proposals have been read, the current accepted level from 2008 is definitely a step in the right direction. Just out of curiosity, I took the liberty of pulling up the annual report for Bellingham’s ozone air quality (graph shown above), which shows extremely excellent ozone air quality, well below the accepted level set by the EPA. County | Measurement in PPb | Clark | 0.059 | King | 0.074 | Klickitat | 0.064 | Pierce | 0.070 | Skagit | 0.046 | Spokane | 0.068 | Whatcom | 0.057 | As a resident of Washington State, I also wanted to show that all counties from 2004-2006 were all under the accepted level of 75 ppb; King County was the only county that comes close to exceeding the accepted levels.
(Information came from the EPA’s website, but cannot be found as formatted.)

The second type of air pollution I will discuss is particle pollution, or particulate matter. Particle pollution is microscopic and more dangerous for humans to breathe. It occurs when a variety of pollutants are released in a number of ways: released from power plants, industries, buses, and diesel trucks; allergens from fragments of pollen or mold spores; dirt or dust stirred up from vehicles or the wind in treeless, unprotected areas, soil, chemicals, and metals. The particle pollutants that form are sulfur dioxide, nitrogen oxides, carbon dioxide, fine particles, and mercury. The ALA is more concerned with the effects of these particle pollutants because they trigger heart attacks, strokes, irregular heartbeats, and cause lung cancer and premature births. Particle pollution harms people even on days their levels are very low; when they exceed higher levels, particle pollution worsens the symptoms of serious respiratory disorders and causes wheezing and coughing. In 2007, according to a report done by the National Resources Defense Council, about 30,000 people may be dying prematurely each year in the United States (175 each day) from cardio-pulmonary diseases linked to particulate air pollution. In an article written by Jennifer Weeks, in 2001, the Bush administration proposed spending $2 billion over 10 years to develop plants that burn coal more efficiently and produce less pollution, but not without clarifying to Americans “that a lot of our money would be spent on developing clean coal technologies” (Weeks). Though President Bush made millions of Americans second guess the need for a better technology for burning coal, I have yet to find any research that shows the Obama Administration has made a decision on this topic. Instead, I have found that articles claiming the Obama Administration is stalling in dealing with this particular topic; this is definitely not a step in the right direction. Air pollution from ozone pollution and particulate matter causes high levels of carbon emissions to be released into the atmosphere, not only harming humans and living organisms but causing the most amount of damage to the Earth’s atmosphere and contributing to climate change (Morrison). Winter-Koger’s essay mentioned that carbon emissions into the Earth’s atmosphere had increased by 31% since 1750 (Winter-Koger, 15). A more current measurement of carbon emissions into the Earth’s atmosphere is now monitored by the CO2 NOW Organization at the Mauna Loa Observatory in Hawaii; recording levels of carbon emissions still increasing year after year since they went online just a few years ago. In February 2010, the amount of carbon emissions measured 389.91 parts per million (ppm); the amount of carbon emissions shown from documents in 2001 measured 371.07 ppm (CO2). Carbon emissions are needed to trap greenhouse gases in the atmosphere, creating the greenhouse effect necessary to stabilize atmospheric temperatures and maintain a climate suitable for life on this planet; however, levels in the upper atmosphere of over 350 ppm are not considered safe or ideal. The affects of this higher measurement is shown with global warming and changing climate temperatures. Winter-Koger’s mentioned the Bush administration “reduced funding for research into cleaner, more efficient vehicles. The EPA, as you may remember is an agency that was set up by the White House and Congress in 1971 to repair damage done to the environment and set new criteria and standards for all Americans to follow in order to provide a cleaner environment. To ensure the EPA does its job, Congress enacted the Clean Air Act, revising it several times since 1955, and requiring the EPA seek approval from Congress first before setting new standards. With just two years under his presidency, on December 7, 2009, "the Obama administration's decision to comply with the Clean Air Act and move forward with a process that can lead to large reductions in greenhouse gas pollution is a major step forward in the fight to stabilize the climate” marked another important change in U.S. history. With this announcement and unilateral authority, the EPA wasted no time in publicly announcing that greenhouse gases to be toxic to human health and the environment. The EPA can now set new standards for carbon emissions for power plants, factories, and cars without the approval from Congress; a decision that has brought new hope to many legislators and weariness to many others. President Obama can now oversee new federal standards on auto emissions and mileage for cars and light trucks with the help from the EPA and the Transportation Department, with an average of 35 miles per gallon taking effect in 2012. This may seem like such a long time before any changes are made, but the healing process does take time. These problems did not occur overnight, and unfortunately, they will not be repaired overnight. We ALL choose to pollute our environment on a daily basis; we should ALL be held responsible in making the environment cleaner. President Obama is definitely leading us in a more positive direction to finding positive solutions to air pollution by holding all accountable their actions.

The Air We Breathe

...The Air We Breathe Air pollution is a serious problem around the world and action should be taken to reduce the pollutants put into the atmosphere to have better air quality, reduce acid rain, and put an end to global warming. Air pollution is the contamination of the atmosphere by different types of wastes and an air pollutant is any substance in the air that have have negative effects on humans and the environment. The different types of wastes includes, gases, liquids, and solids, and can all be formed by things such as: burning of fossil fuels, agricultural activities, exhaust from factories, mining operations, and indoor air pollution. Gaseous wastes are produced by combustion and industrial processes. Combustion is the process of burning something, e.g., engines, incinerators, coal-fired electrical generating plants, and natural causes like forest fires. The six major toxins released into the air are: ozone, particulate matter, carbon monoxide, nitrogen oxides, sulphur dioxide, and lead. Ozone is a gas that can be found near the ground and is a major part of smog.Ozone is formed by a reaction when nitrogen oxides and organic compounds mix in sunlight. Ozone near the ground can lead to health problems such as more frequent asthma attacks in people who have asthma and can cause sore throats, coughs, and breathing difficulty. Ozone can also hurt plants and crops. Particulate matter is very small fragments of solid materials or liquid droplets suspended in air. fine......

...Migration Strategies and Solutions Taekwonda Bowman 10/18/2011 SCI/275 Laquoyah McDaniel The atmosphere is full of many pollutants that affect our health. Air pollution has been a problem for a very long time. No one really seems to think that the little things that they do hurt the air that we breathe. We deal with pollutants inside and outside of the home. Some are self-made and others due to nature, or natures creatures. Every day, the average person inhales about 20,000 liters of air.  Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere.  These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors.  Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time ( The biggest source of air pollution comes from fossil fuels, burning power plants and automobiles. These two contribute to about 90% of the pollution that is in the air. Too many vehicles and factories that run off of fossil fuels omit so much pollution that it create health problems for people, or make existing health problems worse. Even the chemicals that we use to clean our homes or wash our cars release toxins in the air that pollute the atmosphere. Cars give of lots of pollutants due to gas consumption and if the car is not kept up, the engine release old oils or......

Business Economics

...among alternatives involves three ideas central to economics: scarcity, choice, and opportunity cost. Scarcity Our resources are limited. At any one time, we have only so much land, so many factories, so much oil, so many people. But our wants, our desires for the things that we can produce with those resources, are unlimited. We would always like more and better housing, more and better education—more and better of practically everything. If our resources were also unlimited, we could say yes to each of our wants—and there would be no economics. Because our resources are limited, we cannot say yes to everything. To say yes to one thing requires that we say no to another. Whether we like it or not, we must make choices. Our unlimited wants are continually colliding with the limits of our resources, forcing us to pick some activities and to reject others. Scarcity is the condition of having to choose among alternatives. A scarce good is one for which the choice of one alternative requires that another be given up. Consider a parcel of land. The parcel presents us with several alternative uses. We could build a house on it. We could put a gas station on it. We could create a small park on it. We could leave the land undeveloped in order to be able to make a decision later as to how it should be used. Suppose we have decided the land should be used for housing. Should it be a large and expensive house or several modest ones? Suppose it is to be a large and......

...Air pollution is a major health risk concern globally. As industries and large developments continues, urban areas are subject to an increase of potential hazardous air pollution (BMC Public Health, Aug 2006) Reports has showed that carbon monoxide, sulphur dioxide, nitrogen dioxide are just some of the reasons for hospital admissions for cardiovascular and respiratory diseases as well as ongoing health concerns. (BMC Public Health, Aug 2006) Respiratory symptoms in young children has become a major concern. Indoor pollution India has become a major concern for air pollution because they are exposed to some of the highest pollution levels in the world. Because of their cooking, using fuel, adult women and young children are the highest to be exposed to pollution causing acute respiratory infections (ARI) chronic obstructive pulmonary diseases (CORP) and lung cancer. Improvements are being looked at for stoves with chimneys and other factors that may lower the risk of exposures.

Biology as Aqa

...How do we breathe in and out? Breathing is a process that moves air in and out of the lungs. It is the only process that delivers oxygen to where it is needed in the body and removes carbon dioxide. Each breathing cycle involves two stages; * Inhalation (inspiration) when lungs expand and air is pulled into them * Exhalation (expiration) when the lungs reduce in volume and air leaves the lungs. Inhalation and exhalation are produced by movements of two sets of muscles; the diaphragm and the muscles between the ribs which are known as the intercostal muscles. Internal intercostal muscles are used for inhalation and the external intercostal is used during exhalation. Breathing out is easier since both gravity pulling the ribs down and the elasticity of the lungs aid to collapse the lungs and squeeze air out. Humans generally breathe with the diaphragm and external intercostal muscles only, it is only when exercising that we use other muscles. During exercise, it is very significant that your breathing rate is matched to your activity because during exercise you will need extra oxygen; therefore, the body makes the lungs take in more ait to supply. Breathing in; Inhalation * When you inhale, your diaphragm tightens and moves downwards. This therefore increases the space in your chest cavity, into which your lungs expand. Breathing out; Exhalation * When you exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal......

...sustainability issue because they use large amounts of water and create harmful air pollution. “Burning fossil fuels to generate electricity pollutes our air, and contributes to global warming, and consumes vast amounts of water—harming our rivers and lakes and leaving less water for other use” (Environment Ohio Research & Policy Center, 2013). This is an environmental sustainability issue because using up all of the water supply so that others are short on the use of water is not fair to both parties involved. The issue causes many different problems to the environmental because it uses too much water, and pollutes the air people breathe every day. The pollution can cause many types of chronic disease among children and adults who spend a large amount of time outdoors. The issue is that people are not supposed to use more than we have so that we can help our future generations still have the resources we have today. At this rate, power plants are going to affect the environment in a very huge way because it uses lots of water to help with cooling at the plants. It also pollutes the air so it is a leading cause in global warming from polluting the air people are breathing. Also, power plants create harmful air pollution that can cause chronic disease among children and adults. Power plants using fossil fuels to generate electricity pollutes the world, which in return affects everyone that breathes air.

...AND DEATH, ON BREATHING by Aristotle translated by G. R. T. Ross 1 WE must now treat of youth and old age and life and death. We must probably also at the same time state the causes of respiration as well, since in some cases living and the reverse depend on this. We have elsewhere given a precise account of the soul, and while it is clear that its essential reality cannot be corporeal, yet manifestly it must exist in some bodily part which must be one of those possessing control over the members. Let us for the present set aside the other divisions or faculties of the soul (whichever of the two be the correct name). But as to being what is called an animal and a living thing, we find that in all beings endowed with both characteristics (viz. being an animal and being alive) there must be a single identical part in virtue of which they live and are called animals; for an animal qua animal cannot avoid being alive. But a thing need not, though alive, be animal, for plants live without having sensation, and it is by sensation that we distinguish animal from what is not animal. This organ, then, must be numerically one and the same and yet possess multiple and disparate aspects, for being animal and living are not identical. Since then the organs of special sensation have one common organ in which the senses when functioning must meet, and this must be situated midway between what is called before and behind (we call 'before' the direction from which sensation comes, 'behind'......

The Anatomy and Physiology of the Respiratory System

...meatuses. And the job of those meatuses is to almost act as though they're speed bumps. So as soon as you sucked the air in through our nostrils, the air will get caught around the meatuses. It slows the air flow down. And when it slowed the air flow down, it will allow time for the nasal cavity to filter and humidify the incoming air. Because the air in our environment is much drier than the inside of our body. So when we breathe air in, if we didn't humidify a little bit, it would potentially dry out our nasal passages. So as soon as we breathe the air in, the nasal cavity will moisten it up, filter it, and then send it down to the deeper parts of the respiratory tract. So again, those meatuses act as sped bumps. They're going to kick up turbulence in the air to sallow us to filter and humidify better. And we know that the air we take in is humidified because if breathed into your hand. And next we have the hard and soft palate, which you should still be familiar with from API. The hard palate if what we call the roof of our mouth. And the palate here is made up of the maxillary bone and the palatine bone. And then hanging off the hard palate, we have the soft palate, which is made up of cartilage. That's why it's called soft because it's much more flexible. Hard palate, maxillary bone and palatine bone. And then soft palate, which is made up of cartilage. We then have the internal nares.

There were a few amendments to the Clean Air Act in the following years to come, one being in the year 1977 and the other coming in 1990. Although having control over pollution did not just start in 1970 the United States Government stated with a clean act in 1955 which started paving the way for today’s Clean Air Act.(EPA) In the year of 1955 the United States enacted the first pollution control act this act was called the Pollution Control Act of 1955. This act was the first federal regulation for air pollution and the Pollution Act of 1955 also gave funding to help find the main sources of air pollution that was contaminating the air. Before the federal government enacted this act there were several state and local regulations to help with pollution control.(Encyclopedia of Earth) Next came the Air Quality act of 1963, The Air Quality Act of 1963 was an act that authorized a national program to address pollution related environmental problems.(EPA) The act also helped expand research into air quality.

Global Warming

...concede that cities may be heating up because they are growing in size. Moreover, concrete and steel readily absorb the sun’s heat and tend to cool down slowly at night. But urban reading’s, do not reflect the trend in rural areas and can distort global statistics(Awake, 2008;4). A reason given for such changes is an intensification of the green house effect. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere and about seventy-percent is absorbed, heating air, land and sea (National Geographic, 2007). The heat and light can get through the atmosphere, but it can’t get out due to the change in the composition of the atmosphere by pollutants which cause less heat to escape. As a result, the temperature rises. Greenhouse effect is a result of greenhouse gasses; greenhouse gasses are gasses in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot, .Another green house effect enhancing factor seems to be the rising population of farm animals, whose digestive processes produce Methane and Nitrous Oxide. A UN report in 2001 produced by several hundred of the world’s leading Meteorologists suggested from the use of computer generated models, that a further rise of 5.8 degree could take place before the end of this century, replacing previous predictions of......

...brings oxygen into our bodies, which we need for our cells to live and function properly b. and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The Upper Airway and Trachea When you breathe in, air enters your body through your nose or mouth. From there, it travels down your throat through the larynx (or voicebox) and into the trachea (or windpipe) before entering your lungs. All these structures act to funnel fresh air down from the outside world into your body. The upper airway is important because it must always stay open for you to be able to breathe. It also helps to moisten and warm the air before it reaches your lungs. The nose, pharynx, larynx, trachea Sand bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia, it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. The Lungs Structure The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product. We each have two lungs, a left......

Air Around Us

...AIR AROUND US All organisms on Earth need air to survive. Air is present all around us. Air occupies space. Q.1. What is air? Mention some of its components. Air is a mixture of several gases. Some of the components present in air are:  Oxygen  Carbon dioxide  Nitrogen  Dust  Water vapour Q.2. What is atmosphere? A thick blanket of air surrounding the Earth’s surface is called atmosphere. Q.3. How can you demonstrate the presence of air? OR Air occupies space. Explain. When we immerse the open end of an empty bottle into a bucket of water, it is observed that water does not enter the bottle as all the space inside the bottle is taken up by air. But, when we tilt the bottle, air rushes out from the opening and water rushes in to fill the empty space. Q.4. What is ozone layer? Mention its use. The Earth’s atmosphere has a layer of ozone gas. This layer is called the ozone layer. It protects us from the harmful ultraviolet rays of the sun, thus preventing many eye problems and skin cancer in human beings. Q.5. Write a short note on the composition of air. Air mainly contains nitrogen and oxygen. The percentage of nitrogen is 78% and that of oxygen is 21%. Carbon dioxide, noble gases, traces of water vapour, ozone, dust particles and other gases make the remaining 1% of air. Following is the Pie-chart of the composition of air. Q.6.

Air Pollution

...This essay is about Air Pollution, Sources of Air Pollution and Effects of Air Pollution Air pollution is the presence of abnormal concentration and abnormal constituents in air. We know that Fresh air is needed for a healthy life. That is why people go out for morning walks so that they can breathe as much fresh air as possible. But the quality of the air has been deteriorating in urban areas. It is being polluted by smoke, harmful gasses, dust articles and other matters. The burning of petrol and diesel in running vehicles emits carbon monoxide, sulphur dioxide and unburnt hydrocarbon particles. These pollutants are released in the air breathe. They are very harmful for out health. The burning of various fuels in factories and power plants emit carbon monoxide carbon dioxide and other poisonous gases that are left off in the atmosphere. Yet without burning fuel, the production of goods in industries is not possible. So the growth of industrial production is at the cost of polluting air. Various chemical industries such as those manufacturing acids, plastics, dyes and paint, paper, pesticides, petrochemical emit hazardous fumes and gases such as sulphur dioxide, nitrogen oxides, hydrocarbons and fluorocarbons. Industrial dust also causes air pollution.

Briefly Describe the Importance of the Interaction Between the Respiratory and Cardiovascular Systems in Maintaining the Body’s Internal Balance

...of the interaction between the respiratory and cardiovascular systems in maintaining the body’s internal balance” In answering this question we must first have an understanding of how the respiratory system and the cardiovascular system operate independently of each other. The cardiovascular system The cardiovascular system refers to the heart, blood vessels and the blood. Blood contains oxygen and other nutrients which the body needs to survive. The body takes these essential nutrients from the blood. The body gets rid of waste products, such as carbon dioxide, back into the blood, in order to remove them. The main function of the cardiovascular system is to sustain blood flow across all areas of the body. Veins return used blood (deoxygenated) from the body back to the heart. This blood is low in oxygen as it has been used in the function of the body, and is also high in carbon dioxide (the waste product that the body has gotten rid of). The veins carry this deoxygenated blood to the superior and inferior vena cava which then drain into the right atrium. The right atrium pumps blood into the right ventricle. The right ventricle then pumps blood to the pulmonary trunk, via the pulmonary arteries and into the lungs. In the lungs the blood is enriched with oxygen that we breathe in and gets rid of carbon dioxide, which we breathe out. From the lungs, blood drains into the left atrium and is then pumped into the left ventricle. The left ventricle then pumps this......
